I broke up with my emotionally-off, irritating, and rude girlfriend several months ago. Since then, my life has been a whole lot better... but for whatever reason, whenever I see or hear about her, I get very irritated like I did when I dated her. I know for a fact that I'm not interested in her romantically, because if I were, I would have already gotten back into contact with her. I mean, I still could. Now it appears that she may have a thing with someone else. For whatever reason, this irritates the living hell out of me, just as seeing her face or hearing her talk irritates me. Obviously this is more irritating, but it's all the same, nonetheless. Can someone explain what's going on? Again, I would like to emphasize that I have no interest in her anymore, since I was the one who broke up with her. In fact, for a while after we broke up, she still wanted to get back together.
